MOOG Greaseable Universal Joint for Chevrolet Silverado 1500 — Model 355, Cold-Forged Cups & Grease Zerk

MOOG 355 is a greaseable premium universal joint designed to restore driveline articulation and longevity for Chevrolet Silverado 1500 models that use this size U-joint.

Built from cold-forged bearing cups, a carburized heat-treated cross and nitrile rubber grease seals, this MOOG premium U-joint is engineered for strength and serviceability. The greasable design lets technicians and DIYers flush contaminants and add fresh lubricant, while double-lip seals keep dirt and moisture from degrading the bearings. MOOG tests components extensively during development to ensure consistent fit and long-term reliability on compatible vehicles.

How does a greaseable MOOG U-joint help vehicle longevity?

A greasable U-joint extends service intervals by allowing fresh lubricant to displace debris and old grease from bearing surfaces. Regular greasing reduces metal-to-metal wear and helps prevent premature bearing failure without replacing the entire joint.

• Greasable fitting provides access for periodic maintenance
• Fresh grease flushes contaminants from bearing cups
• Durable materials resist wear under load
• Seals minimize ingress of dirt and moisture

Will this MOOG 355 fit my Chevrolet Silverado 1500?

Fitment depends on the drive shaft and yoke dimensions specific to your Silverado 1500 year and trim. Always verify vehicle details—year, make, model, engine and trim—against a fitment guide or the seller's confirmed-fit tool before purchasing to ensure compatibility.

• Confirm cross-to-cap size and snap-ring style on your driveshaft
• Check whether your vehicle requires a greasable or non-greasable U-joint
• Use vehicle-specific fitment tools or contact MOOG if unsure
• Reference any qualifier notes or fitment callouts provided by the seller

What materials and design features deliver strength in this part?

MOOG manufactures the bearing cups by cold-forging, then case-hardens and precision-grinds them for tight tolerances. The steel cross is forged and carburized, giving it high fatigue resistance under torque, while nitrile rubber double-lip seals protect the bearings from contaminants.

• Cold-forged bearing cups for dimensional strength
• Carburized, heat-treated cross for fatigue resistance
• Nitrile rubber double-lip seals to block dirt and moisture
• Greasable zerk to permit scheduled lubrication

How simple is installation and routine maintenance?

MOOG designs these premium U-joints for straightforward replacement using standard hand tools and a press or U-joint tool for cup installation. Greasing is quick: apply lubricant through the zerk, cycle the joint to work grease into bearings, and wipe away excess to keep contaminants off the seal.

• Installation requires a press or appropriate U-joint driver tools
• Follow torque and fitment specs for your driveshaft yokes
• Service by greasing at recommended intervals extends life
• Inspect seals and caps during routine maintenance checks

Who is this for? This MOOG 355 greaseable premium universal joint is intended for owners and mechanics of Chevrolet Silverado 1500 vehicles that match the part's size and snap-ring configuration, and for anyone who prefers serviceable driveline components. It's a good choice for drivers who regularly tow or haul, fleet managers seeking consistent parts quality, and DIY technicians who want a U-joint that can be maintained with grease rather than replaced at the first sign of wear. Before ordering, verify vehicle fitment using the seller's confirmed-fit tool or MOOG fitment resources to ensure the correct application.
